18/1.] DR. J. ANDERSON ON INDIAN REPTILES. 207 



He describes the colour above as olive greenish, much darker and 

 almost black in some male specimens ; upper glandular folds pale ; 

 upper lip whitish ; lower glandular tubercles usually pure white ; 

 sides of body, including the loreal region, black, which uniform 

 colour, however, fades on the posterior part of the body, and is 

 sometimes replaced there by a few dark spots ; lower parts more or 

 less mottled with black, sometimes almost wholly black in the males, 

 hut yellowish between the thighs ; in the females the lower parts 

 are whitish, either uniform or only slightly dusky ; fore limbs with 

 few indistinct cross hands ; a dark streak in front of the upper arm, 

 and another one hehind, as well as on the lower arm ; hind limbs 

 above banded with brown, behind indistinctly mottled with dark 

 and yellow. 



Dr. Stoliczka was at first inclined to regard this species as a variety 

 of H. tytleri (? erytlircea), from which he now considers it to he 

 distinguished by its " larger tympanum, the usual total want of the 

 short downward bent lower glandular fold, the better-developed disks 

 of the fingers and toes, the greater length of the third finger, the 

 presence of two almost subequal metatarsal tubercles, its distinctly 

 larger gape, and more distant vomerine ridges."

Polypedates maculatus, Gray ; Gthr. I. c. p. 428. 



The Darjeeling specimens of this Frog now before me are all more 

 or less distincty spotted on different shades of grey. The largest 

 is pale, almost cream-colour, with very indistinct spots, and no 

 trace of a band between the eyes, and without an hourglass-marking. 

 The brown band along the canthus rostralis and over the tympanum, 

 however, is very distinct. The other two specimens are dark slaty, 

 with indications of the hourglass-marking on the anterior part of the 

 back ; and in both the transverse band between the eyes faintly shows. 



This is not an uncommon species about an elevation of 3000 feet 

 in Sikkim, and is chiefly found among long grass, and not, as its name 

 (Tree-Frog) would lead us to expect, on trees. This is the case also 

 with Rhachophorus maximus, which is found in similar situations, also 

 in ponds and wells. It likewise possesses the power of changing its 

 colours. 



Polypedates quadrilineatus, Wiegm. 



The dark bands are very narrow and not very distinct ; and the 

 black edging can hardly be said to exist. The bands also show a 

 tendency to break up posteriori)', and over the sacrum they are 

 reduced to small black spots. The black band from the snout and 

 over the tympanum is prolonged along the side to almost halfway 

 between the axilla and groin, but behind that it is reduced to 

 widely distant black spots with white edges. The general colour is 

 a pale olive-grey ; the bars on the legs and the marbling on the 

 back of the thighs are well marked, especially the latter. A dark 

 band edged anteriorly with white runs along the back of the fore- 

 arm to the little finger ; the under surface of the lower jaw is finely
